Just checked in some updates to the xulref at
www.mozilla.org/xpfe/xulref. I'm calling it the fifth draft, and I have
already zipped up a new copy. It has the xul 1.0 changes, for the most
part, plus some other stuff: a broadcaster element description
(finally), the command attribute on many elements, the better
descriptions of the broadcaster/observer relationship in general, some
old attributes removed, etc.
I will still be working on it, but it's xul 1.0 certified, pretty much.
Per Brian King's comments in the tracking bug (bugzilla 24689) I will be
working on some better docs for iframe & browser that take stock of
these elements' recent xbl-ification and the new interfaces this
exposes, plus some better accesskey and key docs, other things.
thanks
